Below is a graph depicting the protein expression levels of Antp and Spalt (a transcription factor) in limb precursor cells in a wildtype grasshopper embryo. Based on the data what is a correct conclusion? Antp is a positive regulator of Spalt; Spalt activates expression of genes that promote antennae formation Antp is a positive regulator of Spalt; Spalt represses expression of genes that promote antennae formation Antp is a negative regulator of Spalt; Spalt activates expression of genes that promote antennae formation Antp is a negative regulator of Spalt; Spalt represses expression of genes that promote antennae formation Antp is a negative regulator of Spalt; Spalt activates expression of genes that promote limb formation • Show less
